Answer:
Blue is produced when mixing cyan and magenta ( removing red and green)
Answer:
0.02
Explanation:
coefficient of kinetic friction = μ
force of friction = Ff
Normal Force = FN, but
FN = -W
Ff = -μFN
so μ = Ff/FN
= 4N/200N
= 0.02.
1 metre per second = 2.237 miles per hour
so 83 m/sec = 185.666 miles per hour !! ...answer !!

Answer:
Wavelength of sound in meters = 1.348 m
Explanation:
Given
speed of sound = 34500 cm
= 345 m
(since 1 cm = 0.01m)
frequency of sound = 256 Hz = 256
Wavelength of sound in meters = ?
We know that all waves have same relationship among speed s, frequency f and wavelength λ, which is given by the equation
v = fλ
Wavelength λ = v/f
= 345 m
/ 256
=1.348 m
Hence wavelength of sound in meters = 1.348 m
